```

Univer Bases core combines a structured-data model with a browser workbench. The model and UI are delivered by two Web SDK packages and operate as an independent `UNIVER_BASE` unit.

## Preset Mode

Univer Bases does not currently provide a dedicated preset. Use plugin mode for both the model and browser UI.

## Plugin Mode

### Installation

Add the two Bases product packages to the Univer runtime described in [Installation & Basic Usage](https://docs.univer.ai/guides/bases/getting-started/installation.md):

#### npm

```bash
npm install @univerjs-pro/bases @univerjs-pro/bases-ui
```

#### pnpm

```bash
pnpm add @univerjs-pro/bases @univerjs-pro/bases-ui
```

#### yarn

```bash
yarn add @univerjs-pro/bases @univerjs-pro/bases-ui
```

#### bun

```bash
bun add @univerjs-pro/bases @univerjs-pro/bases-ui
```

### Product plugin registration

Register the shared runtime, formula engine, and license first as shown in the installation guide, then register the Bases plugins:

```ts
import { UniverBasesPlugin } from '@univerjs-pro/bases'
import { UniverBasesUIPlugin } from '@univerjs-pro/bases-ui'

import '@univerjs-pro/bases-ui/lib/index.css'

univer.registerPlugin(UniverBasesPlugin)
univer.registerPlugin(UniverBasesUIPlugin)
```

`UniverBasesPlugin` registers the Base model, commands, field and view registries, formula integration, and permissions. `UniverBasesUIPlugin` adds the rendered workbench and browser interactions.
